**Algebra**

I have a question-If I'm finding the midpoint between points (4,6) and (-8,-7) it would be (-4/2,-1/2), correct? should I reduce it to (-2,-1/2)

**Algebra II-Reiny could you relook at my comments,please?**

I'm not suppose to copy the coordinates off the unit circle-I'm suppose to actually solve for the coordinates-like how do you get the coordinates for 60 degrees? that's where I'm confused

I posted this earler and you gave me help, could you please check what I did? Thank you If a car drives off a 40 m high cliff with a horizontal velocity of 15 m/s, how far from the base of the cliff will the car strike the ground? Could someone help with the equation, please ...

**Physics-Please check**

So I say: 40 m = 1/2 (9.8) * t^2 40/4.9 = 8.16(t^2) sqrt of 8.16 = 2.86 = time 15 * 2.86 = 42.9 for how far from the base of the cliff the car stuck the ground Is this correct? Thank you for helping- I'm homeschooled and trying to learn Physics on my own
